FOLDING-MACHINE.

Specificationof Letters Patent.

Patented Oct. 11, 1910.

Application filed February 14, 1908., Serial No. 415 .813.

To all whom. it may concern:

llo it known that l. Grzouon \V. SMITH, a citizen of t-hcl'nited States,residing at the city of ('ohoes. in the county of Albany and State ofNew York. have invented certain vnew and useful Improvements in Folding-Machines, of which the following is a specification.

.\l v inventionrclatcs to machines for-folding collar and unit blanks,and the objects of my invention are to construct a foldingover the edgesof the die whilc'thc die remains within the fold. By removing thepressure from the foot pedal the infoldcrs luovc backward from over thedie and the head of the press carrying the die will move upward from thebed of the press, leaving the operator the rt-ease of both hands forhandling the gtxids. Other advantages will be disclosed hereafter. Iaccomplish these objects by means of the mechanism illustrated in theaccompanying drawings, in which: f

Figure 1 is a plan view of my machine with the die head down, the dieresting upon the bed plate. Fig. 2 is a frontelevation. Fig. 4 is adetail view of the wedge-shaped cam used to operate the infolders. Fig.5 is a detail view of a modified form of Fig. 4. Fig. 6 is a section ofthe bed and intolders along .the line X-X- on Fig. 1. Fig. 7 is a detailof the lever and tchgiscoping rod used to raise the bed. Figs. 8 and t)are detail views of the diehcad and die. Fig. 1 is a detail of amodified form of die. Fig. 11 is a diagram showing the manner in whichthe successive operations are performed by means of my machine. l ig. 12is a detail view showing the manner of operating the infoldcrs.

Similar numerals refer to similar-parts throughout the several views. r

In the manufacture of cuffs and collars, the blanks from which they aremade are placed upon the heated bed or support of a folding machine. Thedie or former of the shape (lOFlltCl is then pressed down upon the blankand infolders fold the edges of the blank over the die. while the blankis upon the heated support and press the folds either lmfore or afterthe withdrawal of the die, thus making smooth edges of the goods, readyto be sewed or stitched audit) the shape desired.

ltctcrriug to the drawings, 2 is the frame,

of the machine and is mounted upon the supplemental frame 3. or upon anysultable support. The frame, 2, has pro ecting Iromthe back side thereofthe arms, 1, 4. which contain the bearings for the rocking shaft, 5, towlnch the arms, 6, 6, of the die head, 7, are

attached. To the shaft, 5, is also attached the crank arm, 8.

The top of the frame, 2, has an opening in the center adaptedto receivethe bed plate,10. The normal position of the face of thebed platebcingflush with the surface, 9, of the frame 2. This bed plate, 10, isvertically movable as hereafter described.

Attached to the under side of the bed plate, 10. is a box, 14. in whichare placed suitable resistance coils for generating heat by electricity.'1. he bed plate, 10, forms the top of the box, so that it is readilyheated by the heat generated in the coils.

The portions of the infolders lying over the box ll, are.heated by beingin contact with the bud plate, 10, or may be heated by means ofperforations through the bed l'atc,

allowing' the heated air to pass upwar and come in direct Contact withthe infolders.

The under sides of the infolders, 12, have hollow spaces, 15, adapted toreceive suitable electric heating means. The heating means being for thepurpose of heating-the portions of the infolders which do not lie overthe box, 14, thus providing for the heating of the 'cntire infoldcrs.

- livotcd in the supplemental frame, 3, at i 17 is the foot lever 18,having a pedal portion, 19. Attached to the lever, 18, at 20 are thetelescoping rods, 21 and 22, connecting the foot lever 18 to the levels35. The 16-. vers, 35, being pivoted in the frame, 2, at 36 and 37, andadapted to exert an upward pressure n am the bed plate 10. At point 23is attached the rod, 24. The up or end of the rod. 24, is attached tothe we ge shaped .cam, 25 (Figs. 2 and 3) mounted on the front side ofthe frame, 2.

No. (366,766 issued to John Maitland and \Valter John Beattie, January29th 1901, this invention being intended as an improvement to themachine shown and described in saidpatent. v

Attached to the foot lever, at 31, is the rod, 32, arranged so as totelescope into the spring case, 33, against the pressure of the spring,34. The spring case, 33,bein at tached to the crank arm, 8, on the roering I shaft, Y

()n the face, 9, of the frame, 2, are securely fastened the bracingarms, 40, 11 and 42, adapted to resist any upward motion of theinfolders, 12, 12, while allowing them free lateral movement. I I

The die, 13 is non-collapsible. It consists of a thin sheet of flexiblesteel, preferably about eight mills thick, attached to a suitable head.7. The die may be made in sections for increasing the length tocorrespondwith thesize of the collar or cult which it is desired toproduce. die and head of this type is illustrated in Figs. 8 and 9. ()ra different die may be used foreaeh size or style of collar or end, asdesired.

Fig. 10 illustrates a modification of the die, 13, the steel sheet beinghinged at some flexible spring to return the loose end to a -horizontalposition, the-hinge being so constructed as to allow the end to benddownward but not upward. Tlieabove described dies permit the removal ofthe folded blanks withoutappreciable disturbance of the fold or crease.

The operation of .my collar and 'cufi turner is as follows: The goodscome to the machine thoroughly damped, the operator 1 places the blanksupon the bed, then presses l with his foot upon the pedal, 19. Thisturns the foot lever, 18, upon its pivot, 17, and forces upward the rod,32, against the spring, 31, in the spring case, Thus the spring, 34,forces upward the crank arm on the rocking shaft, 5, causing the diehead, 7, to rotate about its pivotal bearings, 4, 4, and bring Referrinto Fig. 11, the pedal, foot lever, the head ant wedge shapedthe die, 13,into contact with the blanks on the bed, 10. A further motion sition ofthe cam before pressure is exerted on the pedal isiiidicated by dottedhues and marked 1st,- 5

It will be seen that in this position the head v is clear of the bed andample space is provided for'the operator to insert tbe'blanks to befolded. The blanks are placed in the machine in the usual manner Theoperator then presses down with his foot upon the pedal, 19, moving itin rapid successionfrom 1st to 2nd then to 3rd 11 nd to pressure.

- As shown in the drawing when the pedal reaches the position markedSecond the die. head by the action ofthe crank shaft, 8,

spring, 34, rod, 32 and foot lever, 18, has

been forced into contact with the work upon the. bed, 10. This motion ofthe pedal, 19, and footlever, 18, has caused the wedge shaped cam, 25,to be drawn down until the I cam is just starting to act. The movementof the pedalfrom 2nd to 3rd causes the cam to force the connecting rods,26 and 27, to

the crank shafts 30 to turn and force the infolders inward folding thegoods over the edge of the die. Further downward motion of the pedalwill bring the head, 50, of the telescoping rods, 21 and 22, to come incon-.

move outward. These rods in turn causing be applied to the infoldcrs.This being rep sisted' by the bracing arms, 40, 41 and 42 an enormouspressure upon thefold is obtained.

For the purpose of returning the parts to the original or. 1st positionI arrange the If I use the modified form'of cam springs, .to withdrawthe infolders and distance fronr-one end and provided with a p 4 \Vhat Iclaim as my invention and desire to secure by Letters Patent is: 4
